Buddha's Travels and teaching 1

For the remaining 45 years of his life, the Buddha is said to have traveled in the Gangetic Plain, in what is now Uttar Pradesh, Bihar and southern Nepal, teaching a diverse range of people: from nobles to servants, murderers such as Angulimala, and cannibals such as Alavaka. Although the Buddha's language remains unknown, it's likely that he taught in one or more of a variety of closely related Middle Indo-Aryan dialects, of which Pali may be a standardization.
